System identification for teh EC135 has been performed for 60kts forward flight as well as for the hover condition. The complexity of the models ranges from 6-DoF rigid body models to 16 state 11-DoF models that include flapping, dynamic inflow and rotor lead-lag. The identified models are going to be used as a basis for the development of the model following flight control system as well as for the development of controller equivalent turbulence models. For the model following flight control system, flight test with controllers based on the identified models for the forward flight condition have already been performed. For hover, the refinement of the control system is ongoing. A hover model including flapping and dynamic inflow but neglecting the motion in longitudinal direction has been identified and shall form the basis for the development of the turbulence models. The quality of this model can only be assessed once the corresponding flight tests in turbulence are available and the techniques being described will be applies.
